  • Explosive compositions based on time-stable colloidal dispersions
    Patent number: 4357184
    Abstract: A water-in-oil explosive composition based on colloidal dispersions is provided. Unlike conventional emulsion explosive compositions, the microemulsion composition of the invention displays exceptional long term storage stability retaining sensitivity to propagation even in small diameter charges. The composition is also tolerant to doping with further fuel and energy enhancing ingredients. The microemulsion-producing component of the composition comprises a combination of at least one conventional water-in-oil emulsifier and at least one amphiphatic synthetic polymeric emulsifier selected from graft, block or branch polymers.
